Introduction to DPSIR
Framework

What is it?
• A strategy for Integrated
Environment Assessment
(IEA) adopted by European
Environment Agency (EEA)
• As an approach to manage
environmental problems, it
presents:
– indicators needed to enable
feedback to policy makers on
environmental quality
– resulting impact of the political
choices made, or to be made

Example
• Water resource management
– State of waters
• How is it? (nutrients, pesticides, heavy metals, …)
• How much is there? (runoff, availability, demands, …)
– Time trends
• Getting better or worse?
• Within or outside agreed limits?
– What is causing the problems?
– Pressures on the environment
• Human
• Industrial
• Agricultural
– State of actions or policies
• Are they working towards targets?

The state of water is determined by natural factors such as geology and climate and also by
the pressures exerted by human activities. Many of the pressures and the underlying driving
devices and reduction of water leakage in distribution systems.

Informatics & Semantics
• Informatics provides interoperability
among diverse and heterogeneous data
and information sources
• Semantic web technologies capture
knowledge from data
• DPSIR  domain ontology
• Information products (figures, tables)
are produced to present the elements of
DPSIR

Summary
• DPSIR is an approach for
environment/ecosystem assessment.
• It identifies five different classes of
indicators, which can be mapped to the
needs of environmental
management/evaluation.
• Ontology with DPSIR helps.
